Very easy to put together! Comes in a few easily attachable segments. The base is sturdy and wrapped with the carpet on the edges so as not to scratch your floor. The carpet is great and a beautiful grey/beige color that goes with everything. My kitty couldn't wait to play on it! Most cat condos that I have seen are smaller (i.e. smaller cubbies and ledges) but this one is roomy for her and still doesn't take up too much room. Solid construction, clever design, and great materials. So grateful!
